It is necessary to take a procedure of damaging the stop-breaking portion 87, and also when removing the main control board case 32, it is necessary to remove the fixing by the fixing means 122 and open the sealing cover 112. As a result, not only the goto act of opening the board case and replacing the internal ROM with an illegal ROM, but also the goto action of exchanging the control board with the board case, stealing the eyes of others in the game hall for a short time. It is difficult to carry out in the above-mentioned manner, and it is possible to effectively prevent a go-to action due to substrate case replacement and substrate case opening. Further, since the sealing cover 112 only needs to cover the sealing breakage part 87 and its peripheral part, the visibility inside the substrate case is not significantly reduced.

  The fixing means 122 includes a screwing base 104 provided on the case lid 62 side corresponding to the outer side of the sealing pin 85, and a fixing screw 126 that can be screwed to the screwing base 104 from the outer side of the sealing cover 112.

  In the sealing cover 112 of this embodiment, only one sealing cover 112 corresponding to the sealing means 64 being sealed is fixed in a closed state by the fixing means 122, and the other sealing cover 112 is, for example, a cover It is held in an open state by locking means 149 provided on the side wall 124 side of the mounting table 144.

  In addition, the sealing cover 112 is provided between the first cover portion 112a on the front end side covering the main control board case 32 side and the second cover portion 112b on the hinge 148 side covering the cover mounting base 144 side, that is, the cover mounting. A closing breakage portion 142 is provided at a position corresponding to the gap 147 between the table 144 and the main control board case 32. That is, the sealing cover 112 has a cutting opening 150 formed on the cover plate portion 151 corresponding to the gap 147, and the reinforcing ribs 152 outside the cutting opening 150 have a pair of closing damage portions. 142. Note that the locking means 149 is configured by, for example, an engaging claw that can be detachably engaged with the closing breakage portion 142 of each sealing cover 112, and the sealing cover 112 is attached to the peripheral wall 146 of the cover mounting base 144. When they are aligned, the locking means 149 engages with the closing breakage portion 142 to hold the sealing cover 112 in that position.

  The fixing means 122 is provided on the first cover portion 112a of the sealing cover 112, and a pressing pin 141 that presses the sealing pin 85 until it engages with the separation preventing portion 83 when the sealing cover 112 is closed. The sealing cover 112 is fixed in a closed state, and a closing means 143 capable of releasing the fixed state by damaging the closing breakage part 142 is provided. The pressing pin 141 protrudes integrally on the inner surface side of the cover plate portion 151 corresponding to the pressing opening 88 on the main control board case 32 side.

  The closing means 143 is integrally provided on the second cover portion 112b of the sealing cover 112 and the release preventing portion 155 provided on the upper wall 145 of the cover mounting base 144 and is detachably coupled to the release preventing portion 155. And a coupling pin 156. The separation preventing portion 155 includes an insertion slit 161 for the coupling pin 156 formed on the upper wall 145 of the cover mounting base 144 and a pair of elastic engagement portions formed integrally with the upper wall 145 on both sides of the insertion slit 161. 162, and each elastic engagement portion 162 is formed with a guide inclined surface of the coupling pin 156.

Then, one sealing cover 112 corresponding to one sealing means 64 used for sealing the main control board case 32 is rotated around the hinge 148 toward the main control board case 32.

  At this time, the pressing pin 141 presses the sealing pin 85 inward through the pressing opening 88 and the coupling pin 156 enters the insertion slit 161 of the separation preventing portion 155 so that the sealing cover 112 is completely removed. When the sealing broken portion 87 is closed, the sealing pin 85 pressed by the pressing pin 141 is engaged with the separation preventing portion 83 and the coupling pin 156 is engaged with the separation preventing portion 155 so as not to be detached. As a result, the main control board case 32 is sealed by the sealing means 64 and the sealing cover 112 is fixed to the main control board case 32.

  In this state, since the sealing breakage portion 87 of the sealing means 64 is covered from the outside by the cover plate portion 151 of the sealing cover 112, the sealing breakage portion 87 is cut with a nipper or the like as it is, and the main control is performed. The substrate case 32 cannot be opened. In order to open the main control board case 32, it is first necessary to cut off the closing breakage part 142 in the closed state to release the fixation between the sealing cover 112 and the main control board case 32. When the closing breakage part 142 is cut, the first cover part 112a of the sealing cover 112 is separated from the second cover part 112b. Therefore, the first cover part 112a is removed from the main control board case 32 and sealed on the main control board case 32 side. The main control board case 32 can be opened by exposing the portion 87 and cutting the sealing breakage portion 87 corresponding to the sealing means 64 used for sealing.

  Thus, when sealing, the main control board case 32 can be sealed only by closing one sealing cover 112 corresponding to one sealing means 64 used for sealing the main control board case 32. While the sealing cover 112 can be fixed to the main control board case 32 at the same time, when opening, the closing breakage part 142 is damaged and the sealing cover 112 and the main control board case 32 are Since it is necessary to take a procedure of releasing the fixation and further cutting the sealing breakage part 87, it is difficult to perform the work in a short time by stealing the eyes of others in the game hall.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, as in the first embodiment, when the fixing screw 126 is screwed onto the screw base 104 on the substrate case 32 side, the distal end side of the fixing screw 126 presses the sealing pin 85 and engages with the separation preventing portion 83. In such a configuration, the sealing cover 112 only needs to be provided in a state where the substrate case 32 can be attached to and detached from the substrate case mounting plate 60, and the sealing cover 112 does not necessarily need to be opened and closed.

  As in the second embodiment, the fixing means 122 is provided on the sealing cover 112 and presses the sealing pin 85 until it engages with the separation preventing portion 83 when the sealing cover 112 is in the closed state. 141 and the closing means 143 capable of fixing the sealing cover 112 in the closed state and releasing the fixed state by damaging the closing damaged portion 142, the closing damaged portion 142 may damage it. As long as the fixed state of the sealing cover 112 and the substrate case 32 can be released by the above, for example, the shaft portion of the coupling pin 156 may be configured as a closing breakage portion 142 so as to be cut from the outside.

  The present invention can be similarly applied to various substrate cases provided with sealing means in addition to the main control substrate case 32 for storing the main control substrate 31. In the embodiment, an example in which the present invention is applied to a pachinko machine has been described. Needless to say, the present invention can be similarly applied to various game machines such as an arrange ball machine and a slot machine.
